回転する光ディスクを支持する回転軸と、その光ディスク下面に対向する平面を有する支持台と、前記支持台の平面に前記光ディスクの半径方向に沿って設けられたスリットと、前記スリットに沿って移動し、前記スリットを通じて前記光ディスクに記録されたデータを読み出すピックアップユニットとを有する光ディスク装置において、
前記支持台の平面には、前記光ディスクの回転方向に対して前記スリットの直前に、スリットに沿った登り段差が形成されていることを特徴とする光ディスク装置。 An optical disc device having a rotation shaft that supports a rotating optical disc, a support base having a flat surface facing the underside of the optical disc, a slit provided in the flat surface of the support base along the radial direction of the optical disc, and a pickup unit that moves along the slit and reads data recorded on the optical disc through the slit,
An optical disc device, characterized in that a step extending along the slit is formed on the plane of the support base immediately before the slit in the direction of rotation of the optical disc. 前記登り段差は、前記スリットの直前に凸状部を形成することにより形成されることを特徴とする請求項１に記載の光ディスク装置。2. The optical disk device according to claim 1, wherein the ascending step is formed by forming a convex portion immediately before the slit. 前記登り段差は、前記スリットの手前を切り欠くことにより形成されることを特徴とする請求項１に記載の光ディスク装置。2. The optical disk device according to claim 1, wherein the step is formed by cutting out a portion in front of the slit. 前記登り段差は、前記スリットの直前に凸状部を形成するとともに、その凸状部手前を切り欠くことにより形成されることを特徴とする請求項１に記載の光ディスク装置。2. The optical disk device according to claim 1, wherein the step is formed by forming a convex portion immediately before the slit and cutting out a portion in front of the convex portion. 前記登り段差は、前記光ディスクの外周部側ほど小さくなるように形成されていることを特徴とする請求項１乃至４のいずれかに記載の光ディスク装置。5. The optical disk device according to claim 1, wherein the ascending step is formed so as to become smaller toward the outer periphery of the optical disk.
